SSC CHSL 2024 PYQ — Question 55

SSC CHSL - 02 July 2024 - Shift 4 • Quantitative Aptitude • Q55

In ∆EFG, XY ∥ FG, area of the quadrilateral XFGY = 44 m2 . If EX : XF = 2 : 3, then find the area of ∆EXY (in m2 ).

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 8.38.

As seen in the figure

∆FEG ~ ∆XEY ( AA similarity criterion )

Given that

Ar(XYFG) = 44 m2

Let the area of ∆EXY = x

The ratio of the areas of 2 similar triangles is equal to the ratio of the squares of their corresponding sides 

Ratio of EX : EF = 2 :5

Hence, xx+44\frac{x}{x + 44}  = (25\frac{2}{5})2

Solving for x we get

21x = 176

⇒ x = 8.38 

Hence, the area of ∆EXY is 8.38 m2
